Reaction Steps
To a solution of {4-[2-(2,4-dichloro-phenyl)-1-hydroxy-1-trifluoromethyl-propyl]-pyridin-2-yloxy}-acetic acid methyl ester (127 mg) in methanol (2 mL) was added an aqueous solution of NaOH (1N, 0.58 mL) and the mixture was allowed to stir at 55° C. for 2 hours. The pH of the mixture was adjusted to pH 2 with aqueous 1N HCl solution and methanol was removed by evaporation. The aqueous solution was extracted twice with ethyl acetate and the organic layers were washed with brine, dried and evaporated. The residual oil was stirred in hexane (5 mL) over night and the suspension was filtered to give the title compound as a colorless powder (96 mg). MS (m/e): 424.2 (MH)+.
